III. DETAILED DESCRIPTION OF THE INVENTION

Now referring primarily to FIG. 1, which illustrates a method of using aparticular embodiment of the instant selective access system (1) forpermitting selective access to ingestible matter (2), whereby theselective access system (1) includes a container (3) having an interiorspace (4) defined by a side wall (5) disposed between opposing top andbottom walls (6)(7), and an opening (8) disposed within the side wall(5), whereby the opening (8) communicates with the interior space (4).

Further, the selective access system (1) includes a cover (9) slidablyengaged with the container (3), whereby the cover (9) can slide upwardand downward between a first position (10) and a second position (11).In the first position (10), the cover (9) overlays the opening (8),thereby precluding access to the interior space (4). In the secondposition (11), the cover (9) disposes away from or above at least aportion of the opening (8) to permit access to the interior space (4)and particularly, to permit access to ingestible matter (2) disposedwithin the interior space (4).

Still further, the selective access system (1) includes a forcegenerator (12) coupled to the cover (9), whereby the force generator(12) generates a pre-selected force amount (13) which when unopposed,provides the first position (10) of the cover (9). Alternatively, thesecond position (11) of the cover (9) can be provided by a counterforcegenerator (14) which can generate a counterforce amount (15) which canbe greater than the pre-selected force amount (13), thus opposing thepre-selected force amount (13) to dispose the cover (9) away from atleast a portion of the opening (8) to permit access to ingestible matter(2) disposed within the interior space (4).

Again referring primarily to FIG. 1, the selective access system (1) canbe used to facilitate management of one or more targeted animals (16),for example wild boars or feral hogs which can cause agricultural and/orenvironmental damage, by permitting selective access to ingestiblematter (2), such as bait (17) including a toxic agent (18), whileprecluding non-targeted animals (19), such as livestock or wildlifeother than wild boars or feral hogs, from accessing the bait (17)including the toxic agent (18).

As to particular embodiments, the bait (17) including the toxic agent(18) can, but need not necessarily, be akin to the bait disclosed inU.S. patent application Ser. No. 15/241,840, which is herebyincorporated by reference herein in its entirety.

For the purposes of the present invention, the term “selective” meansof, relating to, or characterized by selection, whereby selection meansthe act of choosing something from a group.

For the purposes of the present invention, the term “access” means a wayof being able to get something.

Various directional terms, such as top, bottom, side, front, rear, left,right, lateral, above, below, horizontal, vertical, upward, downward,and the like are used throughout this disclosure to provide a frame ofreference (26) in conjunction with the figures to aid in the reader'sunderstanding of the instant invention, and these directional termsshould not be construed as limiting the scope of the invention orrestricting the invention to the described orientation.

Now referring primarily to FIG. 2A through FIG. 4C, as stated above, theselective access system (1) includes a container (3) having an interiorspace (4) defined by a side wall (5) disposed between opposing top andbottom walls (6)(7). The container (3) can be configured to containingestible matter (2) and specifically, ingestible matter (2) can bedisposed within the interior space (4) and correspondingly, theingestible matter (2) can be surrounded by the side wall (5) and theopposing top and bottom walls (6)(7) except proximate the opening (8)disposed within the side wall (5).

It should be appreciated that the container (3) can have any of anumerous and wide variety of configurations and associated lengths,widths, and heights, sufficient to contain ingestible matter (2). As butone illustrative example, the container (3) can be configured as a cubeor a cuboid, whereby the opposing top and bottom walls (6)(7) can (i) begenerally planar, (ii) dispose in generally parallel spaced apartrelation, and (iii) have a generally horizontal orientation in relationto a support surface (20) which supports the container (3). The sidewall (5), which can also be generally planar, can couple the top andbottom walls (6)(7) and correspondingly, can (i) dispose in generallyorthogonal or perpendicular relation to the top and bottoms walls(6)(7), and (ii) have a generally vertical orientation in relation tothe generally horizontal top and bottom walls (6)(7).

As to particular embodiments, the side wall (5) can be formed from aplurality of side wall components (21)(22)(23)(24) coupled together toprovide the side wall (5). To continue with the illustrative exampleabove whereby the container (3) can be a cube or a cuboid, the container(3) can include opposing left and right side wall components (21)(22),which can (i) be generally planar, (ii) dispose in generally parallelspaced apart relation, and (iii) have a generally vertical orientationin relation to the generally horizontal top and bottom walls (6)(7).

The container (3) further includes an opening (8) disposed within theside wall (5), whereby the opening (8) communicates with the interiorspace (4). The opening (8) can have any of a numerous and wide varietyof configurations and associated dimensional relations sufficient toprovide a pass-through for passing matter, such as ingestible matter(2), out of the interior space (4). Continuing with the illustrativeexample above whereby the container (3) can be a cube or a cuboid havingopposing left and right side wall components (21)(22), the opening (8)can be disposed within a front side wall component (23) which disposesbetween the opposing left and right side wall components (21)(22), orthe opening (8) can span the entirety of a front portion of thecontainer (3) between the opposing left and right side wall components(21)(22) and between the opposing top and bottom walls (6)(7).

Again referring primarily to FIG. 2A through FIG. 4C, as to particularembodiments, the container (3) can include only one opening (8) disposedwithin the side wall (5) between the opposing top and bottom walls(6)(7). For example, a cubical or cuboidal container (3) can have onlyone opening (8) disposed within the front side wall component (23),whereby the side wall (5) additionally includes a rear side wallcomponent (24) which laterally couples the opposing left and right sidewall components (21)(22) together. Thus, in this particular embodiment,the interior space (4) and correspondingly, ingestible matter (2)disposed within the interior space (4), can be surrounded by the frontside wall component (23) except proximate the opening (8) disposedwithin the front side wall component (23), the opposing left and rightside wall components (21)(22), the rear side wall component (24), andthe opposing top and bottom walls (6)(7).

Now referring primarily to FIG. 6A through FIG. 8C, as to otherparticular embodiments, the container (3) can include a plurality ofopenings (8) disposed within the side wall (5) between the opposing topand bottom walls (6)(7). For example, a cubical or cuboidal container(3) can have a first opening (25) disposed within the front side wallcomponent (23), and a second opening (26) disposed within the rear sidewall component (24). Thus, in this particular embodiment, the interiorspace (4) and correspondingly, ingestible matter (2) disposed within theinterior space (4), can be surrounded by the front side wall component(23) except proximate the first opening (25) disposed within the frontside wall component (23), the rear side wall component (24) exceptproximate the second opening (26) disposed within the rear side wallcomponent (24), the opposing left and right side wall components(21)(22), and the opposing top and bottom walls (6)(7).

As to particular embodiments, the left side wall component (21) and aportion of at least one of the front and rear side wall components(23)(24) can be integrated such that the left side wall component (21)and a portion of at least one of the front and rear side wall components(23)(24) are formed as a one-piece construct. Said another way, the leftside wall component (21) and a portion of at least one of the front andrear side wall components (23)(24) can be integrally formed, meaningconnected together so as to make up a single complete piece or unit, orso as to work together as a single complete piece or unit, and so as tobe incapable of being easily dismantled without destroying the integrityof the piece or unit.

Continuing again with the illustrative example above whereby thecontainer (3) can be a cube or a cuboid, a single piece of generallyplanar material having a medial portion disposed between opposing endportions can be bent proximate each end portion such that each endportion disposes in generally orthogonal relation to the medial portion.Following, the medial portion can provide the left side wall component(21), one of the end portions can provide a portion of the front sidewall component (23), and/or the other of the end portions can provide aportion of the rear side wall component (24).

Moreover, the right side wall component (22) and a portion of at leastone of the front and rear side wall components (23)(24) can beintegrated such that the right side wall component (22) and a portion ofat least one of the front and rear side wall components (23)(24) areformed as a one-piece construct. Said another way, the right side wallcomponent (22) and a portion of at least one of the front and rear sidewall components (23)(24) can be integrally formed, meaning connectedtogether so as to make up a single complete piece or unit, or so as towork together as a single complete piece or unit, and so as to beincapable of being easily dismantled without destroying the integrity ofthe piece or unit.

Continuing again with the illustrative example above whereby thecontainer (3) can be a cube or a cuboid, a single piece of generallyplanar material having a medial portion disposed between opposing endportions can be bent proximate each end portion such that each endportion disposes in generally orthogonal relation to the medial portion.Following, the medial portion can provide the right side wall component(22), one of the end portions can provide a portion of the front sidewall component (23), and/or the other of the end portions can provide aportion of the rear side wall component (24).

Now referring primarily to FIG. 5A through FIG. 5H, the selective accesssystem (1) further includes a cover (9) having opposing cover front andrear faces (29)(30) extending to a cover edge which defines a coverperiphery, whereby the cover periphery can define any of a numerous andwide variety of configurations of varying dimensions, depending upon theopening (8) which the cover (9) is configured to overlay when the cover(9) disposes in the first position (10). As shown in the examples of theFigures, the cover (9) can be generally planar, having cover front andrear faces (29)(30) which are correspondingly generally planar andextend to a cover periphery which, for example, can be generallyrectangular; however the instant invention need not be limited to thisparticular configuration.

The cover (9) can be configured to slidably engage with the container(3), whereby the cover (9) can slide (i) upward and downward between thefirst and second positions (10)(11), or (ii) vertically in relation tothe top and bottom walls (6)(7) between the first and second positions(10)(11).

In the first position (10), the cover (9) overlays the opening (8),thereby precluding access to the interior space (4) via the opening (8).Said another way, the cover rear face (30) disposes laterally adjacentto the entirety of the opening (8), thus precluding access to theinterior space (4) via the opening (8).

Now referring primarily to FIG. 2A through FIG. 4C, as to particularembodiments having only one opening (8) which disposes within a frontside wall component (23), when in the first position (10), the cover (8)can cooperate with the front side wall component (23), the opposing leftand right side wall components (21)(22), the rear side wall component(24), and the opposing top and bottom walls (6)(7) to surround theinterior space (4) and correspondingly, ingestible matter (2) disposedwithin the interior space (4).

In the second position (11), the cover (9) disposes away from or aboveat least a portion of the opening (8) to permit access to the interiorspace (4) and particularly, to permit access to ingestible matter (2)disposed within the interior space (4). In other words, the cover rearface (30) does not dispose laterally adjacent to the entirety of theopening (8), thus permitting access to the interior space (4) via theopening (8).

The cover (9) can be configured to slidably engage with the container(3). Particularly, the cover (9) can be slidably coupled to thecontainer (3) between the top and bottom walls (6)(7). As to particularembodiments, the cover (9) can be slidably engaged with the side wall(5).

Again referring primarily to FIG. 2A through FIG. 4C, as to particularembodiments of the container (3) having only one opening (8) whichdisposes within a front side wall component (23), the cover (9) can beslidably engaged with the front side wall component (23) and/or the leftand right side wall components (21)(22). More specifically, a cover leftedge (31) can be slidably engaged with the front side wall component(23) and/or the left side wall component (21), and a cover right edge(32) can be slidably engaged with the front side wall component (23)and/or the right side wall component (22).

Now referring primarily to FIG. 6A through FIG. 8C, as to particularembodiments of the container (3) including a plurality of openings (8),such as a first opening (25) disposed within a front side wall component(23) and a second opening (26) disposed within a rear side wallcomponent (24), the selective access system (1) can include acorresponding plurality of covers (9), such as a first cover (33)disposed proximate the first opening (25) and a second cover (34)disposed proximate the second opening (26). As to these particularembodiments, when each of the first and second covers (33)(34) disposein the first position (10), the first and second covers (33)(34) cancooperate with the corresponding front and rear side wall components(23)(24), the opposing left and right side wall components (21)(22), andthe opposing top and bottom walls (6)(7) to surround the interior space(4) and correspondingly, ingestible matter (2) disposed within theinterior space (4). Additionally, as to these particular embodiments,the first cover (33) can be slidably engaged with the front side wallcomponent (23) and/or the left and right side wall components (21)(22),and the second cover (34) can be slidably engaged with the rear sidewall component (24) and/or the left and right side wall components(21)(22). More specifically, a first cover left edge (31) can beslidably engaged with the front side wall component (23) and/or the leftside wall component (21), and a first cover right edge (32) can beslidably engaged with the front side wall component (23) and/or theright side wall component (22); and, a second cover left edge (31) canbe slidably engaged with the rear side wall component (24) and/or theleft side wall component (21), and a second cover right edge (32) can beslidably engaged with the rear side wall component (24) and/or the rightside wall component (22).

Now referring primarily to FIG. 1, FIG. 3A, FIG. 4A, FIG. 7A, and FIG.8A, the selective access system (1) further includes a force generator(12) coupled to the cover (9), whereby the force generator (12)generates a pre-selected force amount (13). As relates to the presentinvention, selective access to the ingestible matter (2) disposed withinthe container (3) can be accomplished by pre-selecting a force amount ofthe force generator (12) such that only a counterforce generator (14),for example a targeted animal (16), can supply the counterforce amount(15) which can be greater than the pre-selected force amount (13).

Accordingly, only the targeted animal (16) (or a comparable counterforcegenerator (14)) can generate a sufficient counterforce amount (15) tooppose the pre-selected force amount (13) of the force generator (12) toprovide the second position (11) of the cover (9), thereby disposing thecover (9) away from the opening (8) to permit access to ingestiblematter (2), for example bait (17) including a toxic agent (18), disposedwithin the interior space (4).

In contrast, a non-targeted animal (19) may not able to supply asufficient counterforce amount (15) to oppose the pre-selected forceamount (13) of the force generator (12) and consequently, thenon-targeted animal (19) may not able to provide the second position(11) of the cover (9). Correspondingly, the first position (10) of thecover (9) can be maintained, thereby precluding the non-targeted animal(19) from accessing the ingestible matter (2), for example bait (17)including a toxic agent (18), disposed within the interior space (4).

As to particular embodiments, the force generator (12) can be configuredas a weight element (35) which generates the pre-selected force amount(13), whereby the pre-selected force amount (13) corresponds to theweight of the weight element (35) or the force of gravity on the weightelement (35).

As to particular embodiments, the pre-selected force amount (13)generated by the weight element (35) can be selected to require thecounterforce generator (14) to comprise a specific grouping of animals,whereby an individual animal within the specific grouping could supply acounterforce amount (15) which can be greater than the pre-selectedforce amount (13) to dispose the cover (9) in the second position (11),permitting access to ingestible matter (2), for example bait (17)including a toxic agent (18), disposed within the interior space (4).

As to particular embodiments, the specific grouping of animals cancomprise a biological classification of animals, such as a taxonomicrank, whereby the taxonomic rank can be selected from the groupincluding or consisting of: family, genus, and species.

As to particular embodiments, the family can be Suidae, to which pigs orswine belong.

As to particular embodiments, the genus can be Sus.

As to particular embodiments, the species can be Sus scrofa, wherebymembers of this species are commonly known as wild boars or feral hogs.

As to particular embodiments whereby wild boars or feral hogs comprisethe targeted animals (16), the pre-selected force amount (13) of theweight element (35) can be equal to or greater than about 6.8 kilograms(about 15 pounds), which can be opposed by a typical wild boar or feralhog to provide the second position (11) of the cover (9), therebydisposing the cover (9) away from the opening (8) to permit access toingestible matter (2), for example bait (17) including a toxic agent(18), disposed within the interior space (4).

Conversely, a non-targeted animal (19), which may typically be found tocoexist with the wild boars or feral hogs, would not be able to supply asufficient counterforce amount (15) to oppose the pre-selected forceamount (13) of the force generator (12). Following, the non-targetedanimal (19) would not able to provide the second position (11) of thecover (9); thus, the first position (10) of the cover (9) would bemaintained and the non-targeted animal (19) would be precluded fromaccessing ingestible matter (2), for example bait (17) including a toxicagent (18), disposed within the interior space (4).

As but one illustrative example, an exemplary geographical region of theUnited States in which the selective access system (1) may be useful forfacilitating management of targeted animals (16) comprising wild boarsor feral hogs includes Texas, which is home to an estimated 2 millionwild boars or feral hogs (about 50% of all the wild boars or feral hogsin the United States). Within this region, non-targeted animals (19)which may coexist with the wild boars or feral hogs include livestocksuch as cattle, goats, horses, and sheep (as non-limiting examples) andwildlife such as beavers, coyotes, deer, foxes, lizards, rattlesnakes,skunks, tortoises, and turkeys (as non-limiting examples).

As a result, an embodiment of the selective access system (1) useful inthis region would have a pre-selected force amount (13) of the weightelement (35) such that the pre-selected force amount (13) can be (a)lesser than a counterforce amount (15) which can be generated by atypical wild boar or feral hog and (b) greater than a counterforceamount (15) which can be generated by livestock such as cattle, goats,horses, and sheep (as non-limiting examples) and wildlife such asbeavers, coyotes, deer, foxes, lizards, rattlesnakes, skunks, tortoises,and turkeys (as non-limiting examples). Research suggests that a weightelement (35) having a pre-selected force amount (13) in a range ofbetween about 6.8 kilograms (about 15 pounds) to about 15.9 kilograms(about 35 pounds) meets both criteria (a) and (b).

As to particular embodiments whereby wild boars or feral hogs comprisethe targeted animals (16), the pre-selected force amount (13) of theweight element (35) can be in a range selected from the group includingor consisting of: between about 6.8 kilograms and about 8.8 kilograms;between about 7.8 kilograms and about 9.8 kilograms; between about 8.8kilograms and about 10.8 kilograms; between about 9.8 kilograms andabout 11.8 kilograms; between about 10.8 kilograms and about 12.8kilograms; between about 11.8 kilograms and about 13.8 kilograms;between about 12.8 kilograms and about 14.8 kilograms; and between about13.8 kilograms and about 15.9 kilograms. As but one illustrativeexample, the pre-selected force amount (13) of the weight element (35)can be about 8.4 kilograms (about 18.6 pounds).

As to particular embodiments whereby wild boars or feral hogs comprisethe targeted animals (16), the pre-selected force amount (13) of theweight element (35) can be equal to or greater than a weight selectedfrom the group including or consisting of: about 6.8 kilograms; about7.8 kilograms; about 8.8 kilograms; about 9.8 kilograms; about 10.8kilograms; about 11.8 kilograms; about 12.8 kilograms; about 13.8kilograms; and about 14.8 kilograms.

As to particular embodiments, the weight element (35) can be integratedwith the cover (9) such that the weight element (35) and the cover (9)are formed as a one-piece construct. Said another way, the weightelement (35) and the cover (9) can be integrally formed, meaningconnected together so as to make up a single complete piece or unit, orso as to work together as a single complete piece or unit, and so as tobe incapable of being easily dismantled without destroying the integrityof the piece or unit. Accordingly, a cover weight provides the weightelement (35), whereby the cover weight can be provided by the materialwhich forms the cover (9).

As to particular embodiments, the cover weight can be generallyuniformly distributed within a cover periphery (36) which bounds thecover (9). As to particular embodiments of the selective access system(1) having a generally planar cover (9) with generally planar coverfront and rear faces (29)(30), the generally uniform distribution of thecover weight can be provided by a generally uniform cover thicknessbetween the cover front and rear faces (29)(30).

As to particular embodiments, the cover (9) can be formed from steel. Asbut one illustrative example, the cover (9) can be formed from at least14 gauge steel, whereby the cover (9) can have a cover height (37) ofabout 0.63 meters and a cover length (38) of about 0.59 meters, therebyhaving a cover weight of about 8.4 kilograms (about 18.6 pounds).Notably, the instant cover (9) may be in stark contrast to doors ofconventional feral pig bait delivery devices, such as the HOG HOPPER™produced by Animal Control Technologies (Australia) Pty Ltd, whereby thedoor of the HOG HOPPER™ is made from lightweight aluminum and is onlyabout 3.5 kilograms (about 7.7 pounds).

Now referring primarily to FIG. 2A, FIG. 3A, FIG. 6A, and FIG. 7A, theselective access system (1) including the container (3) and the cover(9) can together have a selective access system weight which, eithersolely or cooperatively, can be sufficient to preclude movement of theselective access system (1) when in use, whereby the selective accesssystem weight may preclude lateral movement (39), vertical movement(40), and/or pivotal movement (41). Regarding the latter, the pivotalmovement (41) can be about pivot axes defined or provided by each bottomedge of the container (3), whereby pivotal movement or tipping can bethe result of the application of a tipping force. Because the instantinvention may be used in areas which harbor animals, such as bears, thatmay attempt to tip the selective access system (1), having a sufficientselective access system weight to prevent such tipping can be animportant aspect of the instant invention.

As to particular embodiments, the selective access system weight can beat least about 29.5 kilograms (65 pounds). As to particular embodiments,the selective access system weight can be selected from the groupincluding or consisting of: at least about 29.5 kilograms; at leastabout 30 kilograms; at least about 40 kilograms; at least about 50kilograms; at least about 60 kilograms; at least about 70 kilograms; atleast about 80 kilograms; and at least about 90 kilograms. As but oneillustrative example, the selective access system weight can be about33.5 kilograms (about 74 pounds). As but a second illustrative example,the selective access system weight can be about 57 kilograms (about 126pounds).

As to particular embodiments, like the cover (9), the container (3)including the side wall (5) and the top and bottom walls (6)(7) can beformed from steel. As but one illustrative example, the container (3)can be formed from at least 16 gauge steel.

Now referring primarily to FIG. 2C, FIG. 2D, FIG. 3C, and FIG. 3D, asbut one illustrative example, the container (3) can have a containerheight (42) of about 0.7 meters, a container length (43) of about 0.6meters, and a container width (44) of about 0.35 meters, thereby havinga container weight of about 25.1 kilograms (about 55.4 pounds).Correspondingly, in combination with one of the above-described covers(9) having a cover weight of about 8.4 kilograms (about 18.6 pounds),the selective access system weight can be about 33.6 kilograms (about 74pounds).

Now referring primarily to FIG. 6C, FIG. 6D, FIG. 7C, and FIG. 7D, asbut a second illustrative example, the container (3) can have acontainer height (42) of about 0.94 meters, a container length (43) ofabout 0.6 meters, and a container width (44) of about 0.69 meters,thereby having a container weight of about 40.3 kilograms (about 88.8pounds). Correspondingly, in combination with two of the above-describedcovers (9), each having a cover weight of about 8.4 kilograms (about18.6 pounds), the selective access system weight can be about 57.2kilograms (about 126 pounds).

Of note, the instant container (3) may be in stark contrast to that ofthe HOG HOPPER™ which is made from lightweight aluminum and is onlyabout 20.7 kilograms (about 45.6 pounds).

As to particular embodiments, the selective access system (1) can, butneed not necessarily, further include a cover actuator (45) coupled tothe cover (9) in spaced apart relation, whereby the cover actuator (45)may be useful to facilitate upward sliding travel of the cover (9) todispose the cover (9) in the second position (11), thus permittingaccess to the interior space (4) and particularly, to ingestible matter(2) disposed within the interior space (4).

As but one illustrative example, the cover actuator (45) can beconfigured as an elongate member, such as a rod, which outwardly extendsfrom the cover front face (29) between the cover left and right edges(31)(32).

As to particular embodiments, the selective access system (1) can, butneed not necessarily, further include a stop assembly coupled to theselective access system (1), whereby the stop assembly may be useful tostop or arrest upward sliding travel of the cover (9) relative to thecontainer (3).

Now referring primarily to FIG. 2H, FIG. 3H, FIG. 4C, FIG. 5B, FIG. 5D,FIG. 5E, FIG. 5F, FIG. 6H, FIG. 7H, and FIG. 8C, as to particularembodiments, the stop assembly can include a stop element (46) coupledto the cover (9). For example, the stop element (46) can be fixedlycoupled to the cover (9), meaning that the stop element (46) can beimmovably affixed or joined to the cover (9). Thus, the stop element(46) can move along with the cover (9) during upward sliding travel ofthe cover (9).

Further, the stop assembly can include an engagement element (47)coupled to the container (3). For example, the engagement element (47)can be fixedly coupled to the container (3), meaning that the engagementelement (47) can be immovably affixed or joined to the container (3). Asto particular embodiments, the engagement element (47) can be integratedwith the container (3). For example, the engagement element (47) can beintegrated with the side wall (5) or the top wall (6), meaning that theengagement element (47) and the respective side wall (5) or top wall (6)can be formed as a one-piece construct.

In use, upward sliding travel of the cover (9) can be stopped uponengagement, for example abutting engagement, of the stop element (46)with the engagement element (47). Consequently, the stop assembly canpreclude upward sliding travel of the cover (9) beyond where the stopelement (46) abuttingly engages with the engagement element (47).

Again referring primarily to FIG. 2H, FIG. 3H, FIG. 4C, FIG. 5B, FIG.5D, FIG. 5E, FIG. 5F, FIG. 6H, FIG. 7H, and FIG. 8C, at least one of thestop element (46) and the engagement element (47) can be disposedproximate or on the internal surface of the selective access system (1),as opposed to being disposed proximate or on the external surface of theselective access system (1). Accordingly, at least one of the stopelement (46) and the engagement element (47) can be disposed within theinterior space (4).

For example, the stop element (46) can be configured as a protrusionwhich outwardly extends from the cover rear face (30). Following, whenthe cover (9) slidably engages with the container (3) such that thecover rear face (30) disposes toward the interior space (4), the stopelement (46) can inwardly extends from the cover (9) toward or into theinterior space (4).

As to particular embodiments, both the stop element (46) and theengagement element (47) can be disposed proximate or on the internalsurface of the selective access system (1), as opposed to being disposedproximate or on the external surface of the selective access system (1).Accordingly, both the stop element (46) and the engagement element (47)can be disposed within the interior space (4).

Notably, disposing the stop element (46) and/or the engagement element(47) within the interior space (4) to provide an internal stop assemblycan serve to protect the stop assembly from a force outside of theselective access system (1), as the container (3) and the cover (9)bound or surround the stop element (46) and/or the engagement element(47) and accordingly, preclude access to the stop element (46) and/orthe engagement element (47) from outside of the selective access system(1). The instant internal stop assembly may be advantageous in relationto a stop assembly having one or more components which dispose proximateor on the external surface of the selective access system (1), hereinreferred to as an external stop assembly, which may be relatively easilyaccessible from outside of the selective access system (1). Following,one or more components of an external stop assembly may be more easilyuncoupled from the selective access system (1) by a force outside of theselective access system (1). As an example, an animal outside of theselective access system (1) which is attracted to the ingestible matter(2) disposed within the interior space (4) may provide a sufficientamount of force to uncouple the stop element (46) and/or the engagementelement (47) of the external stop assembly from the selective accesssystem (1), thus permitting the cover (9) to upwardly slide withoutrestriction and even possibly permitting the cover (9) to be uncoupledfrom the container (3), thereby allowing non-selective access to theinterior space (4) and correspondingly, ingestible matter (2) disposedwithin the interior space (4).

Worth mentioning, the instant internal stop assembly may be in starkcontrast to the nudge bar and the upper door stop of the HOG HOPPER™, asboth the nudge bar and the upper door stop are disposed proximate or onthe external surface of the HOG HOPPER™ and in particular, outwardlyextend from the door.

As to particular embodiments, the selective access system (1) can, butneed not necessarily, further include a prop (48) which may be useful tosupport the cover (9) in the second position (11) to permitnon-selective access to ingestible matter (2) disposed within theinterior space (4), for example to train or condition targeted animals(16), such as wild boars or feral hogs, to access and eat ingestiblematter (2) from the selective access system (1). Of note, for thistraining or conditioning, the ingestible matter (2) may comprise bait(17) which does not include a toxic agent (18).

As to particular embodiments, the prop (48) can be configured forreception within a bore (49) disposed within the container (3), forexample within the side wall (5) proximate the cover (9). As but oneillustrative example, the prop (48) can be configured as a discrete pinwhich may or may not be coupled to the container (3).

Upon reception within the bore (49), the prop (48) can support the cover(9) in the second position (11). Upon disengaging the prop (48) from thebore (49), the cover (9) can return to the first position (10).

As to particular embodiments, the selective access system (1) can, butneed not necessarily, further include one or more relatively smallaperture elements (50) disposed within the cover (9) to communicatebetween the cover front and rear faces (29)(30). The aperture elements(50) can be sized to permit air flow between the interior space (4) andthe outside environment, whereby the aperture elements (50) can allowscent or odor associated with ingestible matter (2) disposed within theinterior space (4) to egress from the selective access system (1), whichmay attract a targeted animal (16) to the ingestible matter (2).

As to particular embodiments, the selective access system (1) can, butneed not necessarily, further include an access door (51) coupled to thecontainer (3), for example via pivotal coupling to the top wall (6) ofthe container (3). Upon opening of the door (51) to an open position,the interior space (4) can be accessed, for example to disposeingestible matter (2) within the interior space (4).

As to particular embodiments, the selective access system (1) can, butneed not necessarily, further include a catch (52) and a correspondingcatch-receiving element (53) which may be useful to secure or lock thedoor (51) in a closed position to preclude access to the interior space(4) via the door (51). As but one illustrative example, the catch (52)can be configured as a discrete pin which may or may not be coupled tothe container (3), and the corresponding catch-receiving element (53)can have a catch-receiving element first portion (54) fixedly coupled tothe door (51) and a catch-receiving element second portion (55) fixedlycoupled to the top wall (6) proximate the door (51). Upon alignment ofthe catch-receiving element first and second portions (54)(55) andengagement of the catch (52) with the aligned catch-receiving elementfirst and second portions (54)(55), the door (51) can be secured orlocked in the closed position (11). Upon disengaging the catch (62) andthe catch-receiving element (53), the door (9) can be disposed in theopen position (10).

As to particular embodiments, the selective access system (1) can, butneed not necessarily, further include an anchor assembly (56) which maybe useful to anchor the selective access system (1) to a support surface(20) which supports the container (3), thereby precluding lateralmovement (39), vertical movement (40), and/or pivotal movement (41) ofthe selective access system (1).

As but one illustrative example, the anchor assembly (56) can include ananchor (57), which may or may not be coupled to the container (3), and acorresponding anchor-receiving element (58) fixedly coupled to thecontainer (3), for example proximate the bottom wall (7). Upon receptionwithin the anchor-receiving element (58), the anchor (57) and theanchor-receiving element (58) can anchor the selective access system (1)to a support surface (20).

Now referring primarily to FIG. 2H, FIG. 3H, FIG. 4C, FIG. 6H, FIG. 7H,and FIG. 8C, as to particular embodiments, the selective access system(1) can, but need not necessarily, further include an ingestible matterguiding assembly (59) disposed within the interior space (4), wherebythe ingestible matter guiding assembly (59) may be useful to guide ordirect ingestible matter (2) toward the opening (8).

As but one illustrative example, the ingestible matter guiding assembly(59) can include at least one guide plate coupled to the container (3)and disposed within the interior space (4), whereby the guide plate canextend between the left and right side wall components (21)(22).Further, the guide plate can dispose in angled relation to the frontside wall component (23).

Now regarding production, a method of making a particular embodiment ofthe instant selective access system (1) includes providing a container(3) including an interior space (4) defined by a side wall (5) disposedbetween opposing top and bottom walls (6)(7); disposing an opening (8)within the side wall (5), the opening (8) communicating with theinterior space (4); slidably engaging a cover (9) with the container(3), the cover (9) configured to slide upward and downward between afirst position (10) and a second position (11); whereby in the firstposition (10), the cover (9) overlays the opening (8); and whereby inthe second position (11), the cover (9) disposes away from at least aportion of the opening (8) to permit access to the interior space (4);and coupling a force generator (12) to the cover (9), the forcegenerator (12) generating a pre-selected force amount (13) which whenunopposed, provides the first position (10) of the cover (9).

As to particular embodiments, the method can further include coupling astop assembly to the selective access system (1), the stop assemblyincluding a stop element (46) and an engagement element (47); wherebyengagement of the stop element (46) with the engagement element (47)stops upward sliding travel of the cover (9); and disposing at least oneof the stop element (46) and the engagement element (47) within theinterior space (4).

The method of making particular embodiments of the instant selectiveaccess system (1) can further include providing additional components ofthe selective access system (1) as described above and in the claims.

Now regarding use, a method of using a particular embodiment of theinstant selective access system (1) includes obtaining a selectiveaccess system (1) including a container (3) comprising an interior space(4) defined by a side wall (5) disposed between opposing top and bottomwalls (6)(7); an opening (8) disposed within the side wall (5), theopening (8) communicating with the interior space (4); a cover (9)slidably engaged with the container (3), the cover (9) configured toslide upward and downward between a first position (10) and a secondposition (11); whereby in the first position (10), the cover (9)overlays the opening (8); and whereby in the second position (11), thecover (9) disposes away from at least a portion of the opening (8) topermit access to the interior space (4); and a force generator (12)coupled to the cover (9), the force generator (12) generating apre-selected force amount (13) which when unopposed, provides the firstposition (10) of the cover (9). The method further includes disposingingestible matter (2) within the interior space (4); and disposing thecover (4) in the first position (10).

The method of using particular embodiments of the instant selectiveaccess system (1) can further include using additional components of theselective access system (1) as described above and in the claims.
